BeGone has become quite the thing in 2011. Initially launched as a competent and impressive multiplayer shooter, this browser-based gem quickly grew to become something that could rival a lot of full games. There are now several maps, all nicely balanced, and the presentation has been spruced up considerably.
It's a bit like Counter-Strike, basically - and that's hugely impressive, considering this runs in a nice little window right in the middle of a web page. It's a game that requires some decent skill, which it rewards handsomely. And it keeps getting better and better.
4. Stealth Bastard
Curve Studios. Download it from the official website .
A tactical action-platformer, as if Metal Gear Solid were reimagined in true retro-modern style, Stealth Bastard sees you sneaking past robot guards and security systems that aim to take you out in a millisecond. It's fortunate that you can put your sneaky know-how to use across a variety of beautifully imagined levels.
And if those aren't enough, you can even create your own in an initially confusing but eventually fairly sensible level-editing suite that comes free with the already-free game. It's baffling when a developer releases so much of such quality for no coins at all, but it's probably best not to complain too much, or they might stop.

One of the most joyously creative games of the year regardless of price, Wonderputt is a crazy golf experience like no other. The game plays out on just a single screen, but it's a landscape that changes radically across the 15-or-so minutes it'll take you to see it all.
That might not sound long, but every second of Wonderputt is remarkable: from the changing landscapes, to the immaculate ball physics, to the splendid music that plays throughout. It's an absolute labour of love, a game that seems to have had layer upon layer of attention gifted unto it throughout the course of its development. 18 holes have never been so delightful.

Nous is creepy. This seemingly sentient AI says it's a psychoanalysis system, but it appears to mean you harm. Or does it? It also enjoys confusing you at every turn as it judges your performance across a series of neon-lit and action-packed levels.
The game's ability to craft such an atmosphere from so little is an extraordinary feat, and it's coupled by engaging game mechanics that see you striking a fine balance between killing your foes and turning them into health by herding them through special converters. It's fantastic fun, gorgeously presented, and both captivating and unsettling as the story plays out.
